When to Use the Manual Mode in Buick Excelle's Tiptronic Transmission?

Manual mode must be used when entering underground parking garages, utilizing 1st gear to control speed without needing to brake. Manual mode is essential. When emergency braking is required, downshifting simultaneously can rapidly slow down the vehicle. Downshift before entering curves to let the engine's traction control the speed. Just apply a bit of throttle, and upon exiting the curve, the maintained RPM allows for quick acceleration. Aggressive overtaking. A car's torque, also known as rotational force, is the force applied perpendicular to a lever arm of unit length rotating about an axis.
I've been driving my Buick Excelle for several years, and the manual mode is particularly useful on steep slopes, especially when going downhill. The automatic transmission tends to let the car coast too fast, so I manually shift down to 2nd or 3rd gear to use engine braking for deceleration, reducing brake pad wear. The same goes for uphill driving—shifting to a lower gear provides more power, preventing stalling or slipping. In snowy or rainy conditions, manual speed control enhances traction, preventing tire spin and making driving safer and more stable. I often use this method to control gears when driving on mountain roads or during long trips—simply switch to M mode with the gear lever, which is easy to operate and also helps save some fuel.
